A lot of book clubs are reading The Year of Magical Thinking (Vintage, $13.95, paperback), Joan Didion’s National Book Award–winning memoir of the death of her husband, the writer John Gregory Dunne. And for groups or discussion leaders who would like to read more by Didion, the good choices include Slouching Towards Bethlehemand The White Album, the early nonfiction collections that helped to make her reputation as one of America’s finest prose stylists.

But perhaps the best “next book” is the first chapter of her 1992 essay collection, After Henry (Vintage, $14.95, paperback) www.randomhouse.com/vintage/. Didion writes in the chapter about an early editor of her books, Henry Robbins, who died on his way to work at the age of 51. And her comments on death relate, perhaps more directly than anything she has written, to her views in The Year of Magical Thinking. She also notes, correctly, that the relationship between writers and great editors has little to do with changes in manuscripts:

“The relationship between an editor and a writer is much subtler and deeper than that, at once so elusive and so radical that it seems almost parental: the editor, if he was Henry Robbins, was the person who gave the writer the idea of himself, the idea of herself, the image of self that enabled the writer to sit down and do it.”
